Popular e-cigarette brand causes molecular changes in the lungs
A new study conducted by Canadian scientists suggests that electronic cigarettes may cause cellular and molecular changes in the lungs, warning against vaping products being inert.
A team at McGill University in Montreal found that even exposure to aerosols from one of the most popular e-cigarette brands among youth and young adults had “significant effects”.
After examining mice for a month, findings published in The FASEB Journal reveal that the inhalation of e-cigarette aerosols caused changes in the composition of lung’s immune cells and altered the levels of genes and proteins in the lungs.
Accordong to the study coordinator Carolyn Bagloe, data from the research “further emphasize that these products are not inert and can cause lung damage if used long-term”.
The team investigated the impact of low-level, chronic exposure to aerosol from the JUUL e-cigarettes in mice and found that there was a “significant increase” in neutrophil and lymphocyte populations in the lung lavage. It also showed “some changes” in cytokine mRNA expression and “significant changes” in various biological pathways.
